Stranded wire inserted directly into a screw terminal frays. Loose strands break, bend sideways, or reduce contact area. The QUADRIOS 22C429 converts 2.5mm² stranded wire into a solid pin. Crimp the ferrule onto stripped wire, then insert the pin into any terminal block. The blue insulation follows DIN color coding – anyone servicing the panel later knows the wire gauge immediately.

The tin-plated copper barrel provides low contact resistance and resists corrosion. The polyamide insulation withstands 105°C and prevents accidental shorts between adjacent terminals. The 8mm pin length matches most terminal blocks from Phoenix Contact, Weidmüller, and Wago. Use these in PLC cabinets, relay panels, motor control centers, or any installation where reliable screw terminal connections matter. The bag contains 100 ferrules – sufficient for a small control panel or a machine retrofit.
